I think quoting in AppleScript requires a strategy rather than a solution.
One of my favorite scripting methods involves compiling on the fly using
osascript. For example, it's much easier for me to use the AppleScript
method for mounting network shares than to determine all the information
needed to do that using a shell script:
osascript -e "mount volume \"https://one.place.of.mine/personal/me\"";
Or I can use osacompile to convert any script I've saved in text format into
a script as shown in the following example.
osacompile -o ~/Desktop/afile.scpt ~/Desktop/afile
I've said this before, but if I didn't use Smile for anything else, I would
use it so I could convert text to AppleScript strings with a single
keystroke (⌘⇧')
Sometimes I embed a script in too many layers for that simple operation to
be effective. Under those circumstances, I have usually found it effective
to start with the string conversion in Smile, and then to add backslashes
where I see that backslashes have been already been added by that operation,
one at a time between compile attempts, until I get enough to allow
compilation and to produce the intended results. Sometimes meeting both
those requirements is challenging, but it's often possible to extract a
small part of the script without changing the layer level of the target code
so that that section can be tested.
